If you are satisfied earning 8% compomuded over the next 30 years(hopefully you have that much time to leave your money alone) then invest in equities and hopefully when it comes time that you need to pull some of your gains to supplement your income you dont hit a 2008 becuase then your 8% turns into about 5-6%(great advice). stick with what I'm saying and you will be fine Fertile. invest in yourself, educate yourself in what you are interested in. and hopefully what your interested in, you can control such as real estate, your own business,selling shares of your own company or your own offering, etc. you are an outsider looking in if you throw your 500 bucks into a fortune 500 company and by no means do you have any control whatsoever.

As for investing, I'm looking to try to get some passive/supplemental income, hopefully to replace or reduce the money I need to make as lawyer, which is as you know a tremendous amount of work.  

They talked about the following method for those who don't want to be super active in real estate:Buy one house a year, ensure rent covers all expenses at a minimum Have each house on a 15 or 20 year noteOnce you hit year 16 or 21 (whatever you amortize the loan for), start doing cash out refinancesThis method only requires one house (more would work too) a year, and would greatly supplement or even provide a retirement.  

If you are supplementing properties with money from your w2 job and that goes away you will feel some serious pain.

I have also been a Supplemental Teacher at a public school district for 18 years.

Since I’m new in real estate, and at my age, I would like to generate a supplemental income in my retirement even if it’s just one or two properties a quarter.

My goal for 2018 going into 2019 is to supplement my income. 

Or are you going to have another job and this be supplemental. 

@James Freeman Since you need a 4 bedroom, I would recommend that you look into the possibility of building an ADU, Accessory Dwelling Unit, to help supplement your current income.

HVAC codes are supplemental to the IRC.
